EPDM or modified bitumen roofing has become increasingly popular in recent years. One of the most common roofing difficulties that occur with this sort of membrane according to a roofing contractor is shrinking. It has various possible reasons, including aging of the material, faulty installation and exposure to UV rays. However, thanks to technological developments, shrinkage problems on EPDM roofing have considerably diminished.
Here’s everything you need to know about roof shrinkage.
What Is Roof Shrinkage?
Roof shrinkage occurs when synthetic rubber membranes, most frequently ethylene propylene diene monomer, are used as a roofing material (EPDM). EPDM is a relatively robust rubber membrane that is frequently used to seal automobiles, windows, and, yes, roofs. Despite its superior resilience to other rubbers, EPDM shrinks naturally over time—a process that can be accelerated by a variety of conditions.
EPDM is frequently utilized because it protects more delicate roofing components. However, as EPDM shrinks, those protected materials fail; either as a result of the shrinkage tension or as a result of exposure to the sun, rain, or snow, for example.
What Causes EPDM and Modified Bitumen Roof Shrinkage?
EPDM and modified bitumen roof shrinking is a prevalent concern and it’s mainly caused by three things: age, faulty installation, and UV exposure. When it comes to commercial roofing in the past, shrinkage was a significant problem. While this problem exists today, roof replacement experts claim that technological advances in the roofing business have made it less likely that shrinkage will happen.
How Can You Fix Roof Shrinkage?
Prevent structural damage by conducting a seasonal roof check and identifying any roofing concerns that need to be corrected. A home roofer is well-versed in inspecting and repairing various roof components. All the problematic flashing and curbs will be replaced to relieve pressure, the field sheet will be correctly secured with a RUSS strip, and new flashing will be installed to address a shriveling roof.
How Can Roof Shrinkage Be Prevented?
Expert roofers would confirm that the best approach to avoid shrinkage in modified bitumen roofs is to have them properly installed. During installation, a skilled contractor will alternate the end laps while laying out the material. Roof shrinking can be prevented with an EPDM coating or ballast, which the contractor would likely apply to your roof.
